[DRAFT] feat: new client based on RestSharp #225
Conversation
Some notes: - the old client cannot continue because it uses unmaintained OAuth1.0a lib - the old client has no support for OAuth2 - the old client returns the resource <T> directly (just like Lyo) This is a big problem because (a) it assumes a happy path, always getting 200 OK, and (b) not really giving access to all the headers or letting the OslcClient to be reused. This time we return an IOslcResponse that wraps the original reponse. Using a property for the <T> resource also allows us to be lazy about it. In the future, this allows us to introduce property types for POCOs like OslcLink<T>, where that class would have a method .Dereference(Client c) and that would give you an IOslcResponse, allowing to fully crawl. Two big questions left to figure out are auth and serialisation. For auth, RestSharp has a neatly pluggable Authenticator concept. Unfortunately, it is not a perfect abstraction as Oauth often operates over multiple HTTP requests and requires some interaction. Thus, for the OSLC client we need a bit different abstraction to capture the authn beyond one request. For serialisation, I am not thrilled to see how much code is in the RdfXmlMediaTypeFormatter. I would prefer the logic to be much simpler and to only focus on supporting multiple RDF formats. Historically, serialization support for OSLC SDKs tried to some of the following: - OSLC paging support - should be handled via IOslcResponse - OSLC query response detection - should be handled explicitly by the client making a query and expecting a query response, instead of always checking for it - RDF/XML-ABBREV intercept - this one may be a bit tricky to get rid of due to Jazz - some very clever checks if this class can read/write RDF for some class, mostly due to the likely presence of the RDF-XML/ABBREV reader with an overlapping MIME type. , We need to investigate if ASP.NET or RestSharp allow simple means to select the deserialiser and use that instead.

OSLC4Net_SDK/OSLC4Net.Client.RestSharp/IOslcResponse.cs (2)
6-15: Enhance XML documentation for better IntelliSense support.While the interface is well-designed, the XML documentation could be more comprehensive.
Add property and type parameter documentation:
/// <summary> /// Interface for responses for OSLC resource requests. /// </summary> -/// <typeparam name="T"></typeparam> +/// <typeparam name="T">The type of OSLC resource being requested.</typeparam> public interface IOslcResponse<T> where T : IResource { + /// <summary> + /// Gets the URI of the requested resource. + /// </summary> Uri Uri { get; } + /// <summary> + /// Gets the status of the OSLC response. + /// </summary> OslcResponseStatus Status { get; } }
26-33: Add XML documentation for the Resource property.The interface is well-designed, but the Resource property needs documentation.
/// <summary> /// Interface for a successful OSLC resource request containing a resource in the response. /// </summary> /// <typeparam name="T"></typeparam> public interface IOslcResourceResponse<T> : IOslcResponse<T> where T : IResource { + /// <summary> + /// Gets the OSLC resource returned in the response. + /// </summary> T Resource { get; } }OSLC4Net_SDK/OSLC4Net.DotNetRdfProvider/RdfXmlMediaTypeFormatter.cs (2)
376-380: Consider enhancing error logging for better diagnostics.While the error handling logic is correct, consider enhancing the error message to include more context, especially since this is part of a new RestSharp-based client implementation. This would help in troubleshooting RDF parsing issues.
- formatterLogger.LogError(string.Empty, e.Message); + formatterLogger.LogError(string.Empty, + $"Failed to parse RDF content: {e.Message}. " + + $"Media type: {content?.Headers?.ContentType?.MediaType ?? "unknown"}");
Line range hint
310-380: Consider implementing the TODO for separate RDF format handlers.The current implementation handles multiple RDF formats (RDF/XML, Turtle, OSLC Compact) in a single class. As noted in the TODO comment, separating these into individual classes would improve maintainability and make the codebase more modular. This would align well with the Single Responsibility Principle and make it easier to add support for new formats in the future.
Consider creating an abstract base class or interface for RDF format handling and implement specific handlers for each format. This would also make unit testing easier as each format handler could be tested in isolation.
OSLC4Net_SDK/OSLC4Net.Client.RestSharp/OslcClientSharp.cs (7)
13-13: Consider creating a base class for RestSharp clients without authenticationThe TODO comment suggests considering a base class for all RestSharp clients without authentication. Extracting common functionality into a base class can enhance code reuse and simplify maintenance.
Would you like assistance in designing and implementing this base class?
18-24: Add argument validation forresourceUriIn the
GetResourceAsync<T>method, consider validating thatresourceUriis notnull. This prevents potentialNullReferenceExceptionand makes the method more robust.Apply this diff to add argument validation:
public async Task<IOslcResponse<T>> GetResourceAsync<T>(Uri resourceUri) where T : IResource, new() { + if (resourceUri == null) + throw new ArgumentNullException(nameof(resourceUri)); var request = PrepareGetRequest<T>(resourceUri); return WrapOslcResponse<T>(resourceUri, await Client.GetAsync(request)); }
23-23: Await the asynchronous operation directlyConsider awaiting the
Client.GetAsync(request)call directly to ensure proper exception handling and avoid potential issues with unobserved tasks.Since you're already in an
asyncmethod, you can simplify the return statement:return WrapOslcResponse<T>(resourceUri, await Client.GetAsync(request));However, if
GetAsyncmay returnnull, ensure you handle that case appropriately.
55-62: Make constructorprotectedin abstract classThe class
OslcClientSharpBasicis declared asabstract, but its constructor ispublic. For abstract classes, it's conventional to haveprotectedconstructors since they are intended to be subclassed and not instantiated directly.Apply this diff to change the constructor's access modifier:
-public OslcClientSharpBasic(string username, string password, RestClientOptions? options = null) +protected OslcClientSharpBasic(string username, string password, RestClientOptions? options = null) { var restClientOptions = options ?? new RestClientOptions(); restClientOptions.Authenticator = new HttpBasicAuthenticator(username, password); Client = new RestClient(restClientOptions); }
65-78: Make constructorprotectedin abstract classSimilarly, in
OslcClientSharpOauth10a, the constructor ispublicin an abstract class. Consider making itprotectedto prevent direct instantiation.Apply this diff:
-public OslcClientSharpOauth10a(string key, string secret, string accessToken, +protected OslcClientSharpOauth10a(string key, string secret, string accessToken, string accessTokenSecret, RestClientOptions? options = null) { var restClientOptions = options ?? new RestClientOptions { Authenticator = OAuth1Authenticator.ForProtectedResource(key, secret, accessToken, accessTokenSecret) }; Client = new RestClient(restClientOptions); }
87-88: ImplementIRestSerializerbased onMediaFormatterThe TODO suggests implementing
IRestSerializerbased on yourMediaFormatter. Providing a custom serializer ensures that RestSharp correctly serializes and deserializes OSLC resources according to your specific media types.Would you like assistance in implementing the custom
IRestSerializer?
64-64: Implement an ASP.NET Core server for testing OAuthThe TODO suggests implementing an ASP.NET Core server to test the OAuth dance. This is a valuable step for ensuring that the OAuth authentication flow works correctly.
I can assist with setting up a basic ASP.NET Core server for testing purposes. Let me know if you'd like help with this.

🛠️ Refactor suggestion
Consider expanding the interface for production readiness.
While the current implementation is clean and follows C# conventions, consider adding the following essential features for a more robust client interface:
- Cancellation support via
CancellationToken - Additional HTTP methods (POST, PUT, DELETE)
- Authentication/authorization mechanism
- Resource cleanup pattern (implement
IDisposableif managing connections)
Here's a suggested expansion of the interface:
public interface IOslcClient
{
- Task<IOslcResponse<T>> GetResourceAsync<T>(Uri resource) where T : IResource, new();
+ Task<IOslcResponse<T>> GetResourceAsync<T>(
+ Uri resource,
+ CancellationToken cancellationToken = default) where T : IResource, new();
+
+ Task<IOslcResponse<T>> CreateResourceAsync<T>(
+ Uri resource,
+ T content,
+ CancellationToken cancellationToken = default) where T : IResource, new();
+
+ Task<IOslcResponse<T>> UpdateResourceAsync<T>(
+ Uri resource,
+ T content,
+ CancellationToken cancellationToken = default) where T : IResource, new();
+
+ Task<IOslcResponse> DeleteResourceAsync(
+ Uri resource,
+ CancellationToken cancellationToken = default);
+
+ void SetAuthentication(IOslcAuthentication authentication);

💡 Codebase verification
Error handling needs improvement in GetResourceAsync implementation
The current implementation has several gaps in error handling:
- The
WrapOslcResponsemethod only handles successful responses (status code 200) and throwsNotImplementedExceptionfor all other cases. - While
RestSharpResponseFactory.ResponseStatusFrommaps HTTP status codes to OSLC statuses, these aren't properly handled:- Authentication failures (401)
- Authorization failures (403)
- Client errors (400, 402-499)
- Server errors (500+)
- Network failures
- No specific exception types are defined for different error scenarios.
Recommendations:
- Replace
NotImplementedExceptionwith proper error handling for each status code - Add specific exception types for different failure scenarios
- Handle network and deserialization errors
🔗 Analysis chain
Verify error handling in the implementation.
The interface method should have comprehensive error handling in its implementation for various scenarios:
- Network failures
- Authentication errors
- Invalid resource formats
- Server errors
Let's check the implementation:
Let me analyze the implementation further to verify error handling.
Let me check the RestSharpResponseFactory and OslcResourceResponseSharp implementations to complete the error handling analysis.

Update project type GUID to SDK-style for consistency.
The new RestSharp client project uses the legacy-style GUID ({FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}) while other projects use the SDK-style GUID ({9A19103F-16F7-4668-BE54-9A1E7A4F7556}). This inconsistency might cause issues with modern .NET tooling.

Fix instantiation in OslcResourceResponseSharp<T>
In the constructor of OslcResourceResponseSharp<T>, you are calling ResponseSharpMixin<T>.From<T>(restSharpResponse), but since From<TT> is not implemented, this will result in a NotImplementedException.
After implementing the From<TT> method as previously suggested, ensure that OslcResourceResponseSharp<T> correctly initializes its mixin.
Additionally, verify that all methods in OslcResourceResponseSharp<T> delegate appropriately to the mixin.
Would you like assistance in reviewing and adjusting the implementation?

Implement the From<TT> factory method
The static method From<TT> in ResponseSharpMixin<T> currently throws NotImplementedException. This method is essential for creating instances of ResponseSharpMixin<T> from a RestResponse.

🛠️ Refactor suggestion
Handle unanticipated HTTP status codes gracefully
In RestSharpResponseFactory.ResponseStatusFrom, if the StatusCode does not match any of the specified cases, an ArgumentOutOfRangeException is thrown. This can cause the application to crash on unexpected status codes.
Consider handling unknown status codes by returning a default or unknown status, or by logging a warning. Here's a possible adjustment:
>= 500 and <= 599 => OslcResponseStatus.ServerFault,
- _ => throw new ArgumentOutOfRangeException()
+ _ => OslcResponseStatus.UnknownErrorAdditionally, since there are TODO comments about handling specific statuses like 403, you might want to add explicit cases for them.
Would you like help in refining the status code handling logic?

Replace NotImplementedException with appropriate error handling
The WrapOslcResponse<T> method throws a NotImplementedException when the response status is not Success. Throwing NotImplementedException can be misleading, as it suggests that the method is incomplete.
Implement proper error handling by throwing an exception that accurately reflects the error condition. For example, you could throw an OslcClientException with details from the response.

Ensure proper deserialization of resources
In ResponseSharpMixin<T>, the _resourceDeserialized is initialized with new T(), which means it returns a new default instance instead of deserializing the actual response content. This will lead to incorrect resource handling.
Modify the code to deserialize the resource from the RestSharpResponse. Here's how you can adjust it:
-private readonly Lazy<T> _resourceDeserialized = new(() => new T());
+private readonly Lazy<T> _resourceDeserialized;
+public ResponseSharpMixin(RestResponse restSharpResponse)
+{
+ RestSharpResponse = restSharpResponse;
+ _resourceDeserialized = new Lazy<T>(() => DeserializeFromResponse(restSharpResponse));
+}
+private T DeserializeFromResponse(RestResponse response)
+{
+ // Implement deserialization logic using the custom serializer
+ // For example:
+ // return YourCustomSerializer.Deserialize<T>(response.Content);
+ throw new NotImplementedException();
+}
public T DeserializeResource()
{
Debug.Assert(_resourceDeserialized.Value != null, "_resourceDeserialized.Value != null");
return _resourceDeserialized.Value;
}Would you like help in implementing the DeserializeFromResponse method?

44-45: Encapsulate properties to follow C# conventionsThe properties
GraphandRebuildGraphshould have backing fields or use auto-properties with proper access modifiers to adhere to the C# coding conventions.Consider defining the properties with accessors:
public IGraph Graph { get; set; } public bool RebuildGraph { get; set; }Ensure that the properties are appropriately encapsulated if any custom logic is needed.
95-141: Simplify theCanWriteTypemethod for readabilityThe
CanWriteTypemethod contains complex logic that can be refactored for better readability and maintainability.Consider breaking down the method into smaller helper methods or simplifying the conditional statements.

Avoid overriding obsolete methods
The method GetPerRequestFormatterInstance(Type, HttpRequestMessage, MediaTypeHeaderValue) is obsolete in newer versions of ASP.NET Web API.
Verify if this method override is necessary and if it's compatible with the target framework. If not, consider using SetDefaultContentHeaders or other recommended alternatives.

💡 Codebase verification
Downgrade System.Text.Json and related packages to .NET 8.0
The project is currently targeting .NET 8.0 and netstandard2.x, but uses .NET 9.0.0 preview packages. This mismatch could lead to compatibility issues. Recommend downgrading the following packages to their .NET 8.0 stable versions:
- System.Text.Json
- Microsoft.Extensions.Configuration.Json
- Microsoft.Extensions.DependencyInjection
- Microsoft.Extensions.DependencyInjection.Abstractions
- Microsoft.Extensions.Hosting.Abstractions
- Microsoft.Extensions.Logging.Abstractions
🔗 Analysis chain
Consider using stable version of System.Text.Json
Version 9.0.0 is a preview version as .NET 9 is not yet released. Consider using a stable version unless there's a specific need for preview features.
🏁 Scripts executed

Handle potential null references and exceptions
In the WriteToStreamAsync method, there are several places where null references or exceptions could occur, such as when accessing properties or casting objects.
Ensure that all objects and properties are checked for null before use, and implement appropriate exception handling to prevent runtime errors.

Determine the content type correctly
The current logic for determining the RDF writer based on content.Headers.ContentType.MediaType may not handle all cases, especially if content or content.Headers is null.
Add null checks and consider defaulting to a standard content type if ContentType is missing.

🛠️ Refactor suggestion
Ensure proper asynchronous handling in ReadFromStreamAsync
The method ReadFromStreamAsync uses TaskCompletionSource, which might not be necessary with the async/await pattern.
Refactor the method to use async/await for better readability and to follow modern asynchronous programming practices.
public override async Task<object> ReadFromStreamAsync(
Type type,
Stream readStream,
HttpContent content,
IFormatterLogger formatterLogger
)
{
if (content == null || content.Headers?.ContentLength == 0)
{
return null;
}
try
{
// Existing code...
}
catch (Exception e)
{
formatterLogger?.LogError(string.Empty, e.Message);
return GetDefaultValueForType(type);
}
}| throw new UnsupportedMediaTypeException( | ||
| $"Given type is not supported or is not valid RDF: ${content.Headers.ContentType.MediaType}", | ||
| content.Headers.ContentType); | ||
| } |

Use FormatException instead of UnsupportedMediaTypeException
Throwing UnsupportedMediaTypeException with a formatted string may not be appropriate here.
Consider using a more suitable exception type, such as FormatException, or creating a custom exception to handle this case.
throw new FormatException($"Unsupported or invalid RDF media type: {mediaType}");| private class NonClosingStreamWriter : StreamWriter | ||
| { | ||
| public NonClosingStreamWriter(Stream stream) | ||
| : base(stream) | ||
| { | ||
| } | ||

| { | ||
| // Don't let dotNetRDF writer close the file, but need to flush output. | ||
| Flush(); | ||
| } | ||
| } |

Avoid hiding base class methods
In the NonClosingStreamWriter class, overriding the Close method without calling the base implementation might lead to unexpected behavior.
Ensure that resource cleanup is properly handled or consider a different approach to prevent the stream from closing.

Correct the ImplementsICollection method logic
The ImplementsICollection method checks if a type is an ICollection<>, but the comparison might be inaccurate.
Modify the method to correctly determine if the type implements ICollection<>.
private static bool ImplementsICollection(Type type)
{
return type.GetInterfaces().Any(i => i.IsGenericType && i.GetGenericTypeDefinition() == typeof(ICollection<>));

Return default value correctly on exception
When an exception occurs, ensure that the default value returned matches the expected type.
Verify that GetDefaultValueForType(type) returns the appropriate default value.

Avoid storing HttpRequestMessage in an instance field
Storing HttpRequestMessage (httpRequest) as an instance field can lead to issues because HttpRequestMessage is disposable and may cause unexpected behavior if not handled correctly.
Consider passing the HttpRequestMessage as a parameter to methods that require it, rather than storing it.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
